Patent number: 4478671Abstract: A liquid-adhesive applicator has a hollow cylindrical reservoir formed of a somewhat flexible plastic material and closed at each end by rigid plastic end caps. A stiff but bendable rod axially rotatably supports the reservoir, and is bent to form the shank of a handle for the applicator. The reservoir has a plurality of pairs of slits parallel to the axis of the reservoir and angled inwardly midway between radial and tangential orientation. Molded-on protuberances between the pairs of slits cause the slits to open when the applicator is pressed against a surface, such as the edge of a two-by-four stud, to apply adhesive thereto. In a second species the cylindrical reservoir and the end caps are cemented, or are thermoplastically welded, together; and are further made into a sealed toroidal reservoir by an axial tube that prevents leakage if the reservoir unit is discarded for throw-away replacement by a new head unit.Type: GrantFiled: March 16, 1983Date of Patent: October 23, 1984Inventor: James D. Freeman
